TIME CONTROLLING MECHANISM FOR GAS-COCKS.

SPECIFICATION forming part of Letters Patent No. 773,987, dated November 1, 1904.

' Application filed May 28, 1904. $eria1N0. 210,312. (No model) i all whom, it may concern:

Be it known that 1', CHARLES Ross, a subject of the King of Great Britain and Ireland, and

' a resident of West Ealing, England, have in- Controlling Devices, (for which I have filed an application for British Patent No. 8,394, dated April 12, 1904;) and Ido hereby declare the following to be a full and exact description of the same.

This invention relates to improved apparatus for automatically operating electric switches, gas-cocks, or other like controlling devices at a predetermined time, so as to enable, for example, the lights in a building to be put out when desired without burning to waste or requiring the attention of any one to efiect the same, and has for its object to provide a simple, cheap, and efficient apparatus for the purpose.

To this end the invention consists in operating the switch, gas-cock, or other controller by means of a weight which when the apparatus is set for actuation rests on a support or table held up by an arm or catch controlled by a clockwork mechanism and which when such mechanism releases the table falls sufficiently to operate the switch, cook, or other controller.

On the accompanying drawings, Figure 1 represents a sectional elevation of an apparatus embodying the presentinvention, showing the parts set for operating an electric switch. Fig. 2 represents asectional plan of Fig. 1, showing part of the weight-supporting table broken away. Fig. 3 represents a sectional elevation showing the positionof the parts when the switch has been operated.

(4 represents a casing for containing the parts of the apparatus, which is provided with eyes a for hanging it against a wall and with hinged doors a 64 Z) represents a clockwork mechanism supported by brackets b" or otherwise and provided with a time-dial 5 a time-winding arbor R, an alarm-setting dial 6*, an alarmwinding arbor 6 which rotates in the direcprovided with a shortpeg (Z which is adapted to loosely fit into the hollow end of an arm or catch 0 and to detaohably connect the chain thereto. The arm is pivotally mounted on a stud e, rising from a bracket 6 attached to the casing side, so as to have facility of swinging in a horizontal plane between the box side and an upright (0*.

f is a table hinged to the casing side at f and adapted to be maintained in a horizontal position by the arm 0 when the latter is swung underneath it, Figs; 1 and 2, and to'fall and assume a vertical position when the arm is swung from underneath it, Fig. 3. The table f when in its horizontal position serves to support a weight g, which may be made heavier or lighter to suit various switches and which is connected by a cord or the like it to the handle of the electricv switch 6.

The operation of the improved device is as follows: When it is desired to leave theapparatus to turn out the lights at a predetermined time, the clockwork mechanism is started and the alarm-dial is set so as to release the alarm and cause the arbor b to rotate at such time. The peg of the chain CZ is inserted into the hollow end of the arm 0, and the latter is swung underneath the table, so as to support it and the weight on it. At the given time the alarm is automatically released, and the drum 0 winds the chain 41, so as to swing the arm from underneath the table, which then falls and allows the weight to do likewise and operate the switch as desired, while the chain will disconnect from the arm by the peg d drawing out of its hollow end upon the arm stopping against the upright a and will allow the alarm-arbor to continue to operate and not interfere with the operation of the alarm. What I claim as my invention, and desire to secure by Letters Patent, is

1. In apparatus for automatically operating electric switches gas-cocks or other like controllers at a predetermined time, the combination, with a clockwork mechanism having a rotatable arbor adapted to be automatically operated at a predetermined time, of a drum fast on said arbor, a table adapted to swing in a vertical plane, a catch adapted to swing in a horizontal plane across the path of said table to support or release same, means connecting said drum and catch and adapted to operate said catch and to automatically detach therefrom after said catch has been operated, and a weight supportable by said table and connectible to the operating part of the gas or electric controller and adapted to operate same when the catch is operated and the table is released and falls, as set forth.

2. In apparatus for automatically operating electric switches gas-cocks or other like controllers at a predetermined time, the combination, with a clockwork mechanism having a rotatable arbor adapted to be automatically operated at a predetermined time, of a drum fast on said arbor, a table adapted to swing in a vertical plane, a catch having a hollow end adapted to swing in a horizontal plane across the path of said table to support or release same, means attached at one end to said drum and adapted to be wound thereon when it operates, a short peg attached to the other end of said means and adapted to loosely fit into the hollow end of said catch and connect said means thereto for operating said catch and to automatically disconnect the same after said catch has been operated, and a weight supportable by said table and connectible to the operating part of the gas or electric controller and adapted to operate same when the catch is operated and the table is released and falls, set forth.

3. In apparatus for automatically operating electric switches gas-cocks or other like controllers at a predetermined time, in combination, a table adapted to swing in a vertical plane, a catch adapted to swing in a horizontal plane across the path of said table to support or release same, means adapted to connect said catch to a clockwork mechanism for operating same and to automatically disconnect same after said catch has been operated, and a weight supportable by said table and connectible to the operating part of the gas or electric controller and adapted to operate same when the catch is operated and the table is released and falls, as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
